APPARATUS FOR REMOVING SCALE FROM BO|LERS.'

SPECIFICATION formingpart of Letters Patent No. 262,823, dated August15, 1882.

Application filed April 13, 1882.

To all whom it may concern:

Be it known that I, WILLIAM 0RD, ofBrooklyn, Ouyahoga county, State ofOhio, have invented a new and Improved Apparatus for Bemoving Scale fromBoilers, of which the following is a full, clear, and exact description.

The object of my invention is to prevent the accumulation of sediment orscale in boilers, and to provide for brushing or removing the scale fromthe lower parts of the boiler.

To that end my invention consists of a brushing apparatus which isfitted permanently in connection with the boiler, and operated from theoutside to remove scale and carry it to the mud-chamber, all ashereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both figures.

Figure 1 is a sectional side view of a boiler fitted with my improvedbrushing apparatus; and Fig. 2 is a similar view, showing the brush inposition of use.

A is a boiler of ordinary type, provided with mud-drum a.

B is a brush of steel or other suitable material, shaped to conform tothe interior bottom surface of the boiler and hung on the ends of twowires or flexible rods, 1) b, that pass to the outside through theopposite ends of the boiler, suitable packing-glands being pro vided,asshown at 0, around the rods.

d (Z are rollers to which the ends of the wires I) I) connect, theserollers being provided with crank-handles, so that they may be revolvedby hand.

The brush 'B is formed with the heel 6, projecting at one side, andtaking upon the bottom of the boiler when the brush is moved in (Nomodel.)

| one direction, so as to raise the brush from the surface of theboiler.

To operate the brush it is first drawn back,

ing the roller 61 at the rear end of the boiler. During this backwardmovement the brush rides on the heel portion, and is thus raised fromthe surface of the boiler, so as to have no effect. The front roller, d,is then to be turned to draw the brush forward, as indicated by thearrow in Fig. 2, so that it shall sweep the scale and sediment from thebottom of the boiler and carry it forward and discharge it into themud-drum a. This operation may be performed as often as is necessary.

By the use of this. apparatus the accumulation of sediment or scale uponthe bottom of the boiler will be prevented.

In view of the well-known necessity of keeping boilers free from scale,especially that part of the boiler that is directly over the fire, theutility of this apparatus will be apparent.

My improvement may be applied to any cylindrical or shell boiler.

Having thus described my invention, I claim as new and desire to secureby Letters Paten tl. The apparatus for cleaning boilers, consisting ofthe brush B, provided with the heel 6, wires 1) b, and the rollers d d,combined together and with a boiler, substantiallyas shown anddescribed.

2. The brush B, constructed, substantially as shown, with the heelportion 6, and fitted for boiler, substantially as shown and described.
